Vent Silencers

Vent Silencers

Vent silencers are used in conjunction with systems that utilize a pressure relief valve. Typical applications for vent silencers are in oil and gas processing, industrial processing, chemical processing, heat recovery systems, and steam boilers. Universal's vent silencers are used all over the globe on many applications.

HV Series vent silencers effectively silence high-velocity air, steam, and gas vents and blowdowns to atmosphere where sonic or critical conditions exist in the valve. Typical applications include: steam boiler relief valves superheater header relief valves boiler startup and purge high-pressure air vents natural gas blowdowns switch valves compressor blowoffs autoclaves steam ejectors.

A Complete Solution

Universal's extensive in-house engineering, manufacturing, and testing facilities ensure an optimized process, mechanical and acoustic solution for any application.

Easy To Specify and Order

Vent and blowdown silencers are seldom a simple catalog selection. Usually, the purchaser provides detailed specifications and a system description that enables Universal to design a custom solution. An even easier way is to simply send the valve manufacturer's data sheet for a vent to Universal and the experienced sales staff will recommend a silencer best suited for the application.
